Is the rotatable flower of the mobile phone case risky?

Mobile phone protective case can be divided into: PC case, silicone, leather case, crystal case, clear water case, mesh case, metal case of environmental protection PC case, plastic and carbon fiber, etc. Silicone case is the most widely known mobile phone protective case. Soft and slightly slippery, it has been popular in the market for many years. From shoddy floor goods to well-made personalized brands, the market share has always been leading. Silicone shell became popular when MP3 and iPod became popular because of its obvious cost performance, and was liked by many people. There are two kinds of silica gel shells, one is organic silica gel and the other is inorganic silica gel. Mobile phone silicone covers on the market basically belong to the former. Silica gel has many advantages, such as high temperature resistance, good weather resistance (not afraid of ultraviolet rays or ozone decomposition), good insulation and stable material (not changing with animals). In addition, people choose the silicone case because of its good feel: some mobile phones with stiff keyboards will be improved after covering the silicone case. It can also absorb the impact of some bumps on the mobile phone and reduce the damage to the mobile phone.
